Abstract
The invention relates to the field of lifting devices, in particular to a safe support for a hydraulic lifting platform. The safe support comprises a telescopic sheath and a telescopic rod, wherein the telescopic sheath comprises a sheath body, an electromagnet, a sliding iron core and a reset spring, the cross section of the sheath body is U-shaped and surrounds the telescopic rod, and the upper portion of the sheath body is connected with the lifting platform; the electromagnet is located on the lower portion of the sheath body, the end, close to the telescopic rod, of the sliding iron core is V-shaped, and the sliding iron core is located on the left side of the electromagnet; one end of the reset spring is connected with the electromagnet, the other end of the reset spring is connected with the sliding iron core, the cross section of the telescopic rod is inverse-T-shaped, the lower end of the telescopic rod is connected with a base of the hydraulic lifting platform, the telescopic rod is matched with the telescopic sheath, braking teeth are arranged on the right side of the telescopic rod, and the sliding iron core can be inserted in the braking teeth to prevent the telescopic sheath from getting out of control to slide down. Self-locking of the safe support can be achieved after the platform is stopped, accidents caused by falling of objects on the platform when a lift breaks down are avoided, and the hydraulic lifting platform is made safer and more reliable.
Description
Technical field
The present invention relates to jacking system field, specifically a kind of emergency support of hydraulic elevating platform.
Background technology
Hydraulic elevating platform is a kind of Multifunctional hoisting loading-unload machine equipment, and lifting altitude is not from 1 meter to 30 meters etc.; Hydraulic elevating platform is applicable to automobile, freight container, Making mold, timber is processed, all types of industries enterprise and the flow production lines such as chemical industry is filling, all kinds of table top form (as ball, cylinder, rotating disk, turn to, tumble, flexible) can be equipped with, coordinate various mode (transfer, interlock, explosion-proof), there is the features such as lifting exactly, frequent starting, load carrying ability are large, effectively solve all kinds of lift work difficult point in industrial enterprise, make production operation free and relaxed.But, while object or person are lifted to higher position by hydraulic elevating platform, also make the object be lifted there is the risk of falling; If the object on lifting table falls, not only damage is caused to object, also likely pounds ground people or other object, if on lifting table splendid attire be staff, then can directly damage staff.
Summary of the invention
For the problem that the object on hydraulic elevating platform in prior art or staff may fall because of elevator malfunctions, the invention provides a kind of emergency support of hydraulic elevating platform, self-locking can be carried out after platform stops, avoid causing because of elevator malfunctions the thing that holds on platform to fall and cause accident, make hydraulic elevating platform more safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of emergency support of hydraulic elevating platform, comprise flexible sheath and expansion link, described flexible sheath comprises sheath body, electromagnet, slip iron core and retracing spring, the cross-sectional plane of described sheath body is in " recessed " shape, sheath body is enclosed in expansion link outside, and sheath body top is connected with lifting table; Described electromagnet is positioned at sheath body bottom; Described slip iron core is cuboid, slip iron core and expansion link V-shaped close to holding, and slip iron core is positioned on the left of electromagnet; Described retracing spring one end is connected with electromagnet, and its other end is connected with slip iron core; The cross-sectional plane of described expansion link is in " convex " shape, expansion link lower end is connected with the base of hydraulic elevating platform, and expansion link is formed with flexible sheath and coordinates, the right flank of expansion link is provided with brake tooth, and slip iron core can be inserted on brake tooth to prevent flexible sheath from gliding because of out of control.
Described sheath body length is equal with length of telescopic bar, makes expansion link can just enter sheath body.
The invention has the beneficial effects as follows:
(1) emergency support of a kind of hydraulic elevating platform of the present invention, can carry out self-locking after platform stops, and avoids causing because of elevator malfunctions the thing that holds on platform to fall and cause accident, makes hydraulic elevating platform more safe and reliable;
(2) emergency support of a kind of hydraulic elevating platform of the present invention, reasonable in design, principle is simple, is convenient to promote the use of.
